To all whom it may concern:

Be it known that I, MILFORD G. CHANDLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Fluid-Distributing Mechanism,of which the following is a specification.

My invention relates, more particularly, to mechanism for distributingoil to bearings to be lubricated or fluid-fuel to the cylinders of anengine; and my objects, generally stated, are to provide improvements inthe above-referred to variety of mechanism, and more especially that ofthe lunger type, whereby its construction will be simplified andrendered more economical of manufacture; its operation renderedpositive; provision will be made for quickly regulating the supply offluid, operated on, to all pointsof delivery; uniform flow of fluid toall leads will be eflected; and whereby the amount of fluid distributedby the mechanism will be automatically governed by the speed of theengine supplied with the fluid.

Referring to the accompanying drawings, wherein I have shown Ininvention as embodied in a mechanism or distributing oil through twoleads to bearings or other parts of an engine to be lubricated Figure 1is a view in side elevation of my improved distributing means, a portionthereof being shown in section, the section being taken at the line 1 onFig. 2 and viewed in the direction of the arrow. Fig. 2 is a sectiontaken at the line 2 on Fig. 1 and viewed in the direction of the arrow,the valve-proper being shown in elevation, Fig. 3 is a view like Fig. 2in complete sectional elevation. Fig. 4 is a section taken at the line 4on Fig. 1 and viewed in the direction of the arrow. Fig. 5 is a viewdiagrammatic in character, s owing the connection of my improveddistributing means with the throttlecontrol of an internal-combustionengine for automatically controlling the amount of oil supplied to theparts to be lubricated. Fig. 6 is a broken sectionalview taken at theline 6 on Fig. 4 and viewed in the direction of the arrow,- this viewshowing the relative positions occupied by. the fluid-forcing plunger,the operating means for the latter and the inlet passages of thevalve-proper, when the parts of the distributer are in one position.Fig. 7 is a section taken at the line 7 on Fig. 4 and viewed in thedirection of the arrow, the section being taken through the outlet-portof the valve-proper and showing the position occupied by the latter whenthe several parts illustrated in Fig. 6 are in the position thereinshown. Fig. 8 is a view like Fig. 6 showing the positions assumed by theparts when the plunger-driving eccentric has made a quarter turn fromthe position illustrated in Fig. 6. Fig. 9 is a view like Fig. 7 showingthe position occupied by the outletport of the valve-proper when theparts of the mechanism are in the position illustrated in Fig. 8.

Fig. 11 is a viewlike Fig. 7 showing the position occupied by the outlet-port of thevalve when the parts are in the position illustrated in Fig. 10. Fig. 12is a view like Fig. 6 showing the position occupied by the parts afterthe plunger-actuating eccentric has made threefourths of a revolution.Fig. 13 is a view similar to Fi 7, showing the position occupied by t eoutlet-port of the valve when the parts are in the position illustrated1n Fi 12; Fig. 14 is a view like Fig. 2 of a mod' cation of theconstruction represented in the last-referred to figure; and Fig. 15, aview in end elevation of the structure shown in Fig. 14 illustrating themechanism therein provided for driving the fluid forcing plunger.

The casing of my improved distributing means is represented at 14, thiscasing containing a bore 15, preferably tapered as illustrated in whicha tapered rotatable distributing-member 16 is rotatably mounted, thestem of the member 16 being represented at 17 and journaled in a bearing18 of the casing 14. The member 16 is so proportioned relative to thebore 15 that a chamber 19 will be provided between its inner end (ofsmaller diameter) and the adjacent end- Wall of said bore,.this chambercommuni- I tively, inthe casing 14, the passages 24 and 25, opening intothe bore 15.

The member 16 contains, in its smaller end, peripheral recesses orpockets 26, 27, 28 and 29, the recesses 26 and 28 being out ofcommunication with each other, and the recesses 27 and 29 being incommunication through the medium of a passage 30, the recesses 26 and 28being in communication with the space 19, and consequently the pipe 21,through the medium of passages 31 and 32, respectively, which open atone end into said recesses and at their opposite ends through thereduced end of the member 16, the recesses 26, 27, 28 and 29, beingequidistantly spaced about the periphery of the member 16. A passage 33communicates at one end with the passage 30, and consequently therecesses 27 and 29, and at its other end opens into a recess or pocket34 provided in the periphery of the member 16 at its larger end andadapted to be moved into registration, successively, with the passages24 and 25 when the member 16 is rotated.

Cooperating with the member 16 is a plunger 35 which is guidedlyconfined in a bearing 36, screwed into a socket 37 in the member 14, thebottom of said socket being tapered as illustrated at 38 andcommunicating with a passage 39, which opens through the bore 15 at sucha point as will cause the recesses 26, 27, 2S and 29 to be successivelymoved into registration therewith when the member 16 is rotated. Themember 16 and plunger 35 cotiperate with each other to cause the fluidto be pumped to be subjected to the action of the plunger for.

forcing it through the pipes to the parts-to be lubricated, adescription of the particular mechanism illustrated for accomplishingthis operation being as follows: Journa'led in bearings 41 in the upperend of the casing 14 is a shaft 42 carrying an eccentric 43 into contactwith which the upper end of the plunger 35 is held by a spring 35..- Theshaft 42 may be driven in any suitable manner as through the medium of asuitably driven chain 44 running over a sprocket 45 on said shaft. Wherethe various passages and recesses of the member 16 and thecasing 14 areprovided as illustrated and hereinbefore described, the member 16 shouldrotate at one-half the speed of the eccentric 43, and to this end, Iprovide the gear arrangement illustrated comprising a gear 46 secured onthe shaft 43 and a gear 47 on the shaft 17 meshing with the gear 46, thegear 47 being the larger of the two and the ratio between these gearsbeing two to one.

The operation of the mechanism in so far as it has been described is asfollows: Assuming the parts to be in the position illustrated in Fig. 6,wherein the plunger 35 is centric 43 the plunger 35 rises under theaction of the spring 35 thus drawing fluid from the pipe 21 through thepassage 31 into the recess 26 and into the passage 39 and the cavityabove the latter. Further revolution of the shaft 42 to the right inFig. 6 throughout another quarter revolution carries the eccentric 43 tothe position illustrated in Fig. 10, wherein the plunger 35 is at theextreme end of its upper stroke. Further rotation of the shaft 42 inFig. 6 throughout another quarter revolution carries the eccentric tothe position illustrated in Fig. 12, and the recess 29 into registrationwith the passage 39, the movement of the eccentric 43 as described,causing the plungerto move downwardly. The downward stroke of theplunger 35 from the position illustratedin Fig. 10 to the positionillustrated in Fig. 6 (the intermediate position being represented inFig. 12), causes the fluid which is sucked into the passage 39 and thecavity above the latter, to be forced into the recesses 29 and 27 andout through the passage 33 into the recess 34, from which it escapesthrough the passage 24 into the pipe 22 through which it is conducted tothe part to be lubricated, it being understood that the recess 34 bybeing disposed as illustrated and described will be moved intoregistration with the passages 24 and 25 successively, and that it willregister with one of the passages with each downward movement of theplunger 35 as the latter makes two complete reciprocations' to everyrevolution of the member 16. 1t will, therefore, be readily understoodthat oil will be alternately forced through the pipes 22, and 23, insubstantially equal amounts. Furthermore, it will readily be understoodthat by re-arranging the ports, passages and recesses of the mechanismdescribed, the oil may be forced through any desirable number of leads.Where it is desired to vary the amount of fluid pumped with eachoperation of the device, any suitable means for regulating the stroke ofthe plunger 35 may be employed. I prefer, however, to use the meansillustrated and of which the following is adescription: Rotatablysupported on the shouldered end 48 of the bearing 41 is an eccentric 49of substantially the same diameter as the eccentric 43, the eccentric 49being so positioned that it will extend into the path of upwardmovement'of the plunger 35 and thus limit the movement of the latterdepending upon the position to which the eccentric 49 is adjusted on thebearing 41, it being understood that the eccentric 49 merely acts as astop and prevents the plunger 35 from following 'gine wherein, asis wellunderstood in the art, provision should be made for supplying oilto theparts to be lubricated at relatively greatly increased proportions, thefaster the engine is operated. In the arrangement illustratedthe-eccentric 49 is shown as op-.

eratively connected with the throttle-control of the engine, whereby asthe throttle-opening is increased, the eccentric 49 is shifted to permitthe plunger 35 to have greater upward movement. The intake-pipe of aninternal-combustion engine is represented at 50 and contains a throttle51 connected with the usual throttle-rod 52, and is pivoted at 53 to thecontrolling lever 54 usually provided on an automobile. The eccentric 49is provided with an arm 55 pivotally connected as indicated at 56 with arod 57 which is pivotally connected as indicated at 53 with the lever54.

It will be understood from the drawings and the foregoing descriptionthat actuation of the lever 54 simultaneously operates the throttle 51and eccentric 49 to .cause the stroke of the plunger 35 to be reduced asthe throttle closes and increased as the throttle opens, and thusincreased flow of oil, in any desired proportion, to the parts to belubricated as the engine increases its speed, may be provided for.

Referring to the construction illustrated in Figs. 14 and 15, instead ofdriving the fluid-forcing plunger by means driven from a shaft separatefrom the rotating member 16, requiring the use of gears or other meansto drive these two members, in timed relation to each other, it isdriven by means supported on an extension of the member 16, this memberbeing directly driven from any suitable source, instead of indirectly,as in the construction of the preceding figures. In this constructionthe supply-pipe opens through the casing 14 into an annular channel 55inthe periphery of the member 16,

and the pockets 26 and 28 communicate with the said channel through themedium of short passages 56 in the periphery of the member 16, one onlyof said passages being shown. The small end of the member 16 carries arod extension 57, which is equipped with diametrically opposed cams 58,the smaller end of the casing 14 being of reduced diameter, as indicatedat 57*, to form a bearing surface for an eccentric 59, which correspondswith and operates in the same manner as the eccentric 49. The plunger 35in this construction operates in a passage 60, which corresponds withthe passage 39, its

inner end being in line with the recesses 26, 27, 28 and 29. The plunger35 is held up against the outer peripheries of the cams 58, by means ofa spring 61, and when the member 16, together with its rod-section 57,is rotated in any suitable manner, as through the medium of a sprocket62 secured to the stem 17 of the member 16, it will cause the plunger 35to be given two complete reciprocations upon each complete rotation ofthe member 16, the plunger upon each upward movement, drawing a chargeof oil from the supply thereof into the recess 26 or 28, depending uponwhich one is in registration with the passage 60, and upon each downwardstroke forcing the oil, thus drawn from the supply, into the recess 27or 29, depending upon which one is in registration with the passage 60,and thence into the exhaust recess 34 through the passage 33, from whichit is forced into one or the other of the outlets 24 or 25, dependingupon the position of the exhaust recess 34.

As before stated, my improved mechanism may be used for distributingfuel to the cylinders of an internal combustion engine, it beingrequired, however, when the mechansm is so used, that the member 16 bedriven in any suitable way intimed relation to the movements of thepistons in the cylinders to be supplied with fuel, for .causing'the fuelto enter the cylinders at the proper time.
